老师：Hello, everyone. Welcome to our English class. Today we are talking about Unit 7. What's the highest mountain in the world? This is our third period. By the end of this class, you will be able to. to talk about geography and。 By using comparatives and superlatives and learn more facts about elephants and pandas.
老师：First of all, let's look at the superlative. It's a kind of comparison. Mike is the tallest student in our class. Mike is taller than any other student in our class. No student in our class is as tall as Mike. Mic is much taller than, is almost as tall as Mike. He is one of the tallest students in our class.
老师：同学们请关注这些表达方法，它们的含义分别是，最高的学生比班里其他任何一个学生都高，没有学生跟 Mike 一样高， MIC 比别人高得多，最高的学生之一。我们可以说这些表达方式基本上都是表示了最高级的含义。
老师：Now, everyone, please open your books and turn to a page 52 for a fill in the blanks with the correct forms of the words in the bar.
老师：pass，同学们请按下暂停键，你有 1 分钟的时间。用方框内词的正确形式填空，okay。 Now, let's see. Number one, the Amazon River is one of the longest rivers in the world. It's a little longer than the Yangtze River. number two more llama is eight thousand eight hundred。 And 44 point 43 meters high is one of the most popular places for Sirius mountain climbers. No. 3, no ocean in the world is as big as the Pacific Ocean, the last one. Although Japan is older than Canada, it is much smaller. Now let's move on to the next part. Activity 4B, write two comparisons about two topics, right? True facts. For example, now we have two rivers, the Yangtze River and the Amazon River. Yes, the Yangtze River is almost as long as the Amazon River. The Amazon is longer than the Yanzi, but the Yangtze is the longest river. In China, now, we have two cities, Beijing and Shanghai. Can you write two comparisons about them? Okay, we can say Shanghai has a bigger population then Beijing. Beijing is bigger than Shanghai. And then two animals, elephant and panda. Let's write the comparisons together. An elephant is much taller than a panda. An elephant weighs more than a panda. An elephant eats more food a day than a panda. Okay, everyone, now let's have more practice. Number one, Flat a is more expensive than flat B. It can be. Flat B is less expensive than Flat A. Flat B is cheaper than Flat A. Or flat B is not as expensive as a.
老师：这句话的意思是，公寓 a 比公寓 b 贵。我们也可以写成以下三种形式，第一种， b 没有 a 贵。请同学们关注 less 这个词的用法。第2种， b 比 a 便宜。第3种， b 没有 a 贵。请同学们注意 us as 的意思是和什么什么一样。当我们写成 not as，意思就变成不如 number two i prefer math to English it can be i like math better than English。这句话的意思是，跟英语相比，我更喜欢数学。 prefer to 的用法是和什么什么相比，更喜欢什么什么，所以我们也把它写成 like better than。
老师：Let's see the last sentence. He is the tallest student in the class. It can be. He is taller than any other student in the class.
老师：第三句话的意思很简单，它是班里最高的学生，我们也可以写成在班里，它比其他任何一个学生都高。同学们要注意 any other 后边要跟名词的单数。
